STRIPING ATTACHMENT FOR PAPER-BAG MACHINES.

SPECIFICATION forming part of Letters Patent No. 428,184, dated May 20, 1890.

Application filed August 5, 1889. Serial No. 319,761. (No model.)

To all whom it may concern.-

Be it known that I, THEODORE R. TROEN- DLE, a citizen of the United States, residing at Batavia, in the county of Kane and State of Illinois, have invented certain new and useful Improvements in Striping Attachments for Paper-Bag Machinery, of which the following is a specification.

The object of my present invention is to provide improved means for marking or striping a web of paper out of which bags are to be formed, and said striping mechanism being adapted to be secured on a bag-machine and to operate on the web of paper after it is unrolled and before the bag is completed without interfering with the travel of the paper through the machine or with the operation of forming the bag.

In my application, Serial No. 280,629, filed July 1, 1888, I have described means for imprinting or marking a web of paper out of which a bag is being formed, said means consisting of a rotary impression cylinder or roll and suitable inking which performs the marking, and said application claims, broadly, said impression mechanism.

In my present improvement I provide markin g-pens which are supplied with ink in a novel manner and which are mounted on a bar pivoted at right angles to the direction of movement of the web of paper, the latter being drawn from the roll and guided by suitable rolls geared in unison with the operating parts of the bag-machine, so that the paper travels at a uniform rate of speed through the striping mechanism and the bag-machine, the striping being performed as a part of the continuous operation of forming the bag.

In the accompanying drawings, Figure 1 is a plan view of that portion of a paper-bag machine to which I apply my striping mechanism, and includes, besides said striping mechanism, the pasting-roll and the tuber for forming the paper into a tube. Fig. 2 is a side elevation of the frame-work, the striping mechanism being shown in vertical section on the line 2 2 of Fig. 1.

In the drawings, A represents the frame work of the bag-machine, and B an auxiliary frame-work for supporting the striping mechanism.

0 is the pivoted paper-roll holder; D, the paper-roll; E and F, guide-rolls, and G a bedroll for the marking-pens.

H H are leading-rolls, the surfaces of which impinge upon the web of paper I, which is passed between them. Motion is imparted to said rolls through the bevel-gear J on the shaft K, which carries at its opposite end the bevel-wheel K, geared with the gears on the bag-machine proper.

L L represent additional guide-rolls, and M M the paste-rolls.

N is a bar, which is pivoted at n to a bracket B of the frame B. The upper surface of said bar carries an ink-pad O, and the front edge of the bar carries the marking-pens P, which communicate by the ducts o with the ink-pad O. The ink-pad may be a heavy flannel or felt pad and the ducts 0 narrow strips of the same material leading to the pens. These pens are adapted to bear upon the surface of the web of paper immediately over the bedroll G, and as the paper is drawn taut from the latter said pens mark thereon continuous parallel stripes. A flat bed or surface may be substituted for roll G.

If desired, a reciprocating or alternating vertical movement may be given to the bar carrying the marking-pens, so as to stripe at intervals instead of continuously.

If it be desired to interrupt the striping, the pivoted bar may be secured so as to raise the pens out of contact with the paper by means of the spring-catch Q, which enters the seat q in the frame B.

I claim- The combination, with a bag-machine having a papenroll-supporting shaft and suitable feed and guide rolls for feeding and guiding the web of paper from the roll to the bagforming mechanisms, of a striping mechanism intermediate the roll of paper, and the bagforming mechanism comprising markingpens, ink-supplying devices, and a bed-roll to support the web of paper beneath the pens, substantially as described.
